It is of the the form of
.Do you observe ? where a=\(2^x\)b=\(3^x\)
\(\frac{a^3+b^3+a^2b+b^2a}{a^2b+b^2a}\)=\(\frac{13}{6}\)\(\Rightarrow\frac{a^2+b^2}{ab}=\frac{13}{6}\)\(\frac{a}{b}+\frac{b}{a}=\frac{13}{6}\)let x=a/b then it is a quadratic equation
[/et_pb_tab][et_pb_tab title="Hint 3" _builder_version="3.22.7"]\(6x^2-13x+6=0\)on solving we get x=3/2 or 2/3now replace x by a/b
[/et_pb_tab][et_pb_tab title="Hint 4" _builder_version="3.22.7"]so again putting value of a and b we get final ans is +1 and -1

These courses are B.Stat and B.Math program in I.S.I., B.Sc. Math in C.M.I.
The entrances to these programs are far more challenging than usual engineering entrances. Cheenta offers an intense, problem-driven program for these two entrances.

In 2025, 8 students from Cheenta Academy cracked the prestigious Regional Math Olympiad. In this post, we will share some of their success stories and learning strategies. The Regional Mathematics Olympiad (RMO) and the Indian National Mathematics Olympiad (INMO) are two most important mathematics contests in India.These two contests are for the students who are […]

Cheenta Academy proudly celebrates the success of 27 current and former students who qualified for the Indian Olympiad Qualifier in Mathematics (IOQM) 2025, advancing to the next stage — RMO. This accomplishment highlights their perseverance and Cheenta’s ongoing mission to nurture mathematical excellence and research-oriented learning.

Cheenta students shine at the Purple Comet Math Meet 2025 organized by Titu Andreescu and Jonathan Kanewith top national and global ranks.

Celebrate the success of Cheenta students in the Stanford Math Tournament. The Unified Vectors team achieved Top 20 in the Team Round.
